[Machine] It was narrated from the Prophet ﷺ that he prohibited "tabattul". Ash'ath ibn Abdul Malik contradicted him.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ «نَهَى عَنِ التَّبَتُّلِ» خَالَفَهُ أَشْعَثُ بْنُ عَبْدِ الْمَلِكِ  

It was narrated from Samurah bin Jundab that the Prophet forbade celibacy. Abu Abdur-Rahman said: Qatadah is more reliable and better preserves narrations than Ash'ath but the hadith of Ash'ath (here) appears to be the correct one. Allah, Most High, knows best. (Using translation from Nasāʾī 3214)   

أَنَّ رَسُولَ اللهِ ﷺ «نَهَى عَنِ التَّبَتُّلِ» قَالَ لَنَا أَبُو عَبْدِ الرَّحْمَنِ قَتَادَةُ أَثْبَتُ وَأَحْفَظُ مِنْ أَشْعَثَ وَحَدِيثُ أَشْعَثَ هَذَا أَشْبَهُ بِالصَّوَابِ وَاللهُ أَعْلَمُ  

Sa'd said: “The Messenger of Allah disapproved of Uthman bin Maz'un's desire to remain celibate; if he had given him permission, we would have gotten ourselves castrated.” (Using translation from Ibn Mājah 1848)  

«لَقَدْ رَدَّ رَسُولُ اللهِ ﷺ عَلَى عُثْمَانَ وَهُوَ ابْنُ مَظْعُونٍ التَّبَتُّلَ وَلَوْ أَذِنَ لَهُ لَاخْتَصَيْنَا»  

It was narrated from Anas that there was a group of the Companions of the Prophet, one of whom said: "I will not marry women." Another said: "I will not eat meat." Another said: "I will not sleep on a bed." Another said: "I will fast and not break my fast." News of that reached the Messenger of Allah and he praised Allah then said: "What is the matter with people who say such and such? But I pray and I sleep, I fast and I break my fast, and I marry women. Whoever turns away from my Sunnah is not of me." (Using translation from Nasāʾī 3217)  

أَنَّ نَفَرًا مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ بَعْضُهُمْ لَا أَتَزَوَّجُ النِّسَاءَ وَقَالَ بَعْضُهُمْ لَا آكُلُ اللَّحْمَ وَقَالَ بَعْضُهُمْ لَا أَنَامُ عَلَى فِرَاشٍ وَقَالَ بَعْضُهُمْ أَصُومُ فَلَا أُفْطِرُ فَبَلَغَ ذَلِكَ رَسُولَ اللهِ ﷺ فَحَمِدَ اللهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ «مَا بَالُ أَقْوَامٍ يَقُولُونَ كَذَا وَكَذَا لَكِنِّي أُصَلِّي وَأَنَامُ وَأَصُومُ وَأُفْطِرُ وَأَتَزَوَّجُ النِّسَاءَ فَمَنْ رَغِبَ عَنْ سُنَّتِي فَلَيْسَ مِنِّي»  

It was narrated from Sa'd bin Hisham that he came to the Mother of the Believers, 'Aishah. He said: "I want to ask you about celibacy, what do you think about it?" She said: "Do not do that; have you not heard that Allah, the Mighty and Sublime, says: 'And indeed We sent Messengers before you, and made for them wives and offspring'? So do not be celibate." (Using translation from Nasāʾī 3216)   

سَمِعْتَ اللهَ يَقُولُ {وَلَقَدْ أَرْسَلْنَا رُسُلًا مِنْ قَبْلِكَ وَجَعَلْنَا لَهُمْ أَزْوَاجًا وَذُرِّيَّةً} [الرعد 38]؟ فَلَا تَتَبَتَّلْ
